AAL2 transmitter for voice-packed and signaling management-packed interleaving on an ATM connection

A system for interleaving voice packets and signaling and management packets on an asynchronous transfer mode (ATM) connection, said system comprising:

• a digital signal processor (DSP) system having an input for receiving a voice communication and operably configured to packetize said voice communication and append a corresponding physical phone line identifier;
• a host processor operably configured to enable ATM adaptation layer signaling and management and transmit a corresponding signaling and management packet including a transmit channel identifier;
• and
• an ATM transmitter comprising:
• a first direct memory access unit having an input for receiving a voice packet fetched from said DSP sub-system;
• and
• a second direct memory access unit having an input for receiving a signaling and management packet fetched from said host processor.

A method for transmitting packetized data received from a digital signal processor (DSP) sub-system and a host processor in an asynchronous transfer mode (ATM) system, said method comprising:

• fetching a voice packet from said DSP sub-system, said voice packet including a physical phone line identifier corresponding to an originating voice channel supported by said DSP sub-system;
• forwarding said voice packet to a transmit buffer associated with a identified transmit channel;
• fetching a signaling and management packet from said host processor, said signaling and management packet including a transmit channel identifier;
• and
• forwarding said signaling and management packet to a transmit buffer associated with an identified transmit channel.
